tools
build-vybe-transaction
Build Unsigned Solana Transaction
Builds an unsigned Solana transaction with the Vybe Solana API (see https://docs.vybenetwork.com) for a token swap, a token-account close, or an MEV withdrawal, and returns it as base64 for the user to review and sign in their own wallet. This tool never signs, submits, or broadcasts a transaction, never moves funds on its own, and never accepts private keys. Use query-vybe-api with /v4/trading/swap-quote first when the user only wants a price quote.

pay-with-x402
Pay With X402
Before calling any Vybe endpoint without an API key (e.g. AI agent, throwaway script, premium-only path), use this to access the same endpoint via x402 pay-per-call USDC on Solana.

query-vybe-api
Query Vybe Solana API
Runs a read-only GET request against a documented /v4 path on the Vybe Solana API (see https://docs.vybenetwork.com) and returns live Solana data: token prices, holders, liquidity and candles; wallet balances, PnL, counterparties and DeFi positions; markets, trades, transfers, top traders and labeled accounts. Use list-endpoints or search-endpoints to find a path and get-endpoint to check its parameters first. This tool cannot create, modify, or delete anything.

query-vybe-api-batch
Query Vybe Solana API (Batch Wallets)
Reads Solana wallet data for many addresses in one call from the Vybe Solana API (see https://docs.vybenetwork.com). These endpoints use a POST body only to carry the list of wallet addresses; they do not create, modify, or delete any data. Use query-vybe-api for single-wallet and all other reads.
